CONTINUOUS-RAIL FROG.

SPECIFICATION forming part of Letters Patent N0. 689,296, dated December 17, 1901.

Application filed September To all whom it. may concern.-

Be it known that I, EDWIN S. EBEELEIN, a citizen of the United States of America, residing atAllegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Continuous-Rail Frogs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in continuous-rail frogs, and relates more particularly to that class of frogs placed at the crossings of main and side tracks and wherein the inner rail of the side track crosses or passes through the outer rail of the main track. At suchpoints with the frogs now generally in use an open joint is formed between the inner rail of the side track and the adjoining rail of the side track, and with such frogs guard-rails are necessary in order to prevent the car-wheels from j umping the track by reason of the lateral pressure at these points-an event of frequent occurrence.

The object of the present invention is to provide at the points mentioned-a solid unbroken rail for either the main or side track when the switch is thrown either way and to entirely dispense with the use of guard-rails.

The present invention aims to construct a sliding frog actuated and controlled positively by the movement of the switch-rails; furthermore, one that will be extremely simple in its construction, strong, durable, and comparatively inexpensive to manufacture.

With the above and other objects in view the invention finallyconsists in the novel con-- struction, combination, and arrangement of parts to be hereinafter more particularly described, and specifically pointed out in the claim.

In describing my invention in detail reference is had to the accompanying drawings, formingapart of this specification, and wherein like numerals of reference indicate like Figure-1 is a plan view of the rails with my improved frog and switch attached thereto in operative position. Fig. 2 is an enlarged plan view of the frog. Fig. 3 is a side elevation of the same. Fig. 4 is a plan view of the switch-tongue. Fig. 5 is a side view of the 4,1901. Serial Emmet. on model.)

same. Fig. 6 an end view thereof. Fig. 7 is a plan view of the block upon which the sliding switch-tongue is mounted. Fig. 8 is a fron't'elevation of the same. Fig. 9 is a plan View of the yoke. Fig. 10 is a front view thereof.

In the drawings the reference-numeral 1 represents the main track, while 2 represents the siding-track.

3 represents the switch-rails, and 4 the frog. Said frog is supported upon a base-plate 5, secured upon channel-bars 6. Between these channel-bars is secured a block 7, which is dovetailed.

The reference-numeral 8 represents the switch-tongue, secured upon a sliding plate 9, said sliding plate having formed in its underface a dovetailed guideway 10, forming downwardly-extending ends 11, which are adapted to receive the yoke 12. This yoke likewise carries downwardly-extending ends '14, the said parts 11 and 14. being apertured to receive suitable fastening means, and to the shank portion of said yoke is secured an operating-rod 15, connected to a bell-crank 16, the other end of said bell-crank being connected to a rod 17, formed in several sections and connected together by means of turnbuckles 18. The other end of said rod is connected to a bell-crank 19, which is connected to the switch-rails in any suitable manner. The rods and bell-cranks are operated by means of the ordinary switch stand and lever. (Not shown in the drawings.)

The manner of operating my improved switch-frog will be readily apparent from the foregoing description and by referring to the accompanying drawings.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully'described my invention, what I claim as new, and desire to secure by Letters Patent, is*

In combination with the rails of a main and side track, of a sliding plate'having a dovetail guideway formed on its under face and carrying a switch-tongue on its upper face, a block dovetailed on its upper face on which face said sliding plate is mounted, a baseplate, channel-bars, secured thereto and to said block, a yoke having downwardly-ex- In testimony whereof I affix my signature tending ends dovetailed and secured to the in-the presenoeof two witnesses.

dovetailed ends of said sliding plate, an apertured shank portion on said yoke, an operating-rod engaging in said apertured shank and VVit-nesses:

a bell-crank connected to said rod and to the JOHN NOLAND, switch-rails, substantially as described. H. O. EVERT.
